A rule of thumb is 25lbs per 1/4" of thickness, so for 3/4" would be around 75lbs.
About 75 lbs.
that depends on the type of plywood 3/4" ranges from about 20.00 to about 50.00 a sheet (cheap flooring to higher end finish plywood and marine grade pressure treated) in my area. . .check around.
Trick question! A single sheet of OSB weighs about 1.5 lbs per sf or 47 lbs, assuing you are asking about 7/16" thick, not 716. One sheet of plywood weighs a bit more. There is no such thing as OSB plywood! That is like asking how much does a motorcycle car cost?
when asking this question you first need to take into account that plywood comes in different thicknesses therefore weight per particualr thickness of sheet plywood will vary-- in my opinion/ without fact and research / a sheet of 1/2 inch plywood may way about 16 lbs. while a 3/4 inch plywood sheet may way 70 lbs.

The birch veneer is actually accounts for a small portion of the plywood's density. The core layers are more important. The Purebond plywood that I see at my local home despot is probably from Columbia Forest Products. According to their website, my plywood on the east coast is composed of a combination of aspen and fir layers. Birch has a density of 670 kg/m3, Aspen 420 kg/m3, and Fir 530 kg/m3. If you don't know what kg/m3 means, I did an estimate on the math. Guessing that the board is 2/3 Fir and 1/3 Aspen, and neglecting the millimeter of birch on top, the weighted average density is 494 kg/m3 or about 31 lb/ft3. If you still don't know what lb/ft3 means, basically a 4 by 8 sheet of plywood, 3/4" thick, should weight about 59 pounds. A half inch thick sheet, should weight about 39 pounds; and a quarter inch thick sheet should weigh in at around 18 pounds.
No, not safe; if supported on each end it is likely to break
I need the thickness dimension of 12 ply plywood for floor.
It depends on the type of armor you need: Body Armor: A thick jacket/coat, with many pockets to fill with flat, lightweight objects (such as plywood) Field Armor: (for cover): Large plywood sheets standing uprights with a flat base bolted to the sheet.
A US quarter is 1.75 mm thick. Canadian quarters are 1.58 mm thick.
It depends what the "ply" value is ... the number of layers glued together. For instance, 1/2" plywood is going to be lighter then 3/4" plywood. A common rule of thumb is a 4x8 foot sheet of 1/4" fir plywood weighs 25 pounds. There are 32 square feet in a sheet, so a square foot of 1/4" fir plywood weighs about 0.78 pounds. Since 1/2" is twice as thick as 1/4", 1/2" fir plywood weighs twice as much, or 1.56 lbs, and 3/4" three times as much, or about 2.34 lbs. Fir plywood is common, but other species are available. Weight varies considerably between species of wood, so be aware the weight of plywood of different species can be different.
